1. BELL WORK 9/6/16: Draw the pictures and explain the difference between a monomer and a polymer.

2. Science Fact of the Day: The little Alaskan Wood Frog is capable of reviving itself back to normal life after staying completely frozen for months, during which its heart, brain, and other organs stop functioning.

3. Reminders: 1. Vocab. Definitions due Thursday 2. Vocab. Quiz Thursday 3. Test Re-dos must be done by Friday!

4. This is a great example of what Cornell notes should look like and what I expect.

5. Standard: (9A) The student will compare the structures and functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids
Essential Question: How do the structure and function of carbohydrates and lipids compare?

6. Set up the next page in your journal…
Date:
Title: Lipids
Essential Question: How do the structure and function of carbohydrates and lipids compare?
Yes, Cornell notes!

7. Card sort…
You should be able to have better luck identifying Carbohydrates
You have 2 minutes to find all the carbs….GO!

8. You should have some or all of these…

9. Lipids….here we go!
Structure discovery: Answer the following questions with your partner.
How would you describe the structure (shape) of this biomolecule?
What elements are present?
How do you know for sure that it is not a carbohydrate?

10. Structure:
typically chain shaped
(CHO)
does NOT have a 1:2:1 ratio.

11. all Carbon atoms are bonded to a Hydrogen atom
Two Types of Lipids:
Saturated:
all Carbon atoms are bonded to a
Hydrogen atom
*Saturated fats are usually solids at room temperature

12. Healthier (easier to break double bond)
Unsaturated: not all Carbon atoms are bonded to Hydrogen; double bonds present
Healthier (easier to break double bond)
*Unsaturated fats are usually liquid at room temperature.

13. What do we call the pieces of a lipid?
Monomer =
fatty acid
Three fatty acids bond with a glycerol to form a …
Polymer = triglyceride
or lipid
glycerol backbone with three fatty acid chains

14. Function: Long term energy storage, 9 cal/gram
more bonds = more energy, so they take longer to break apart
main component of the cell membrane (More on this later)
waxy coating (cuticle) on leaves-helps retain water
hydrophobic (Repels Water)
they don’t dissolve in water!

15. CANDLES, EAR WAX, COATING ON FRUITS/VEGGIES
Examples…
WHITE PARTS OF RAW MEAT
Fats
Oils
Waxes
Cell membrane
COMMON COOKING OILS
CANDLES, EAR WAX, COATING ON FRUITS/VEGGIES
LIPID BILAYER

16. What it looks like on a Food Label…

17.
Don’t try this at home!!!

18. Burning Questions…
At the bottom of your notes, answer the following question:
Why does a grease fire burn so much longer than a marshmallow?
Use the words sugar, lipid, bonds, and energy in your answer!

19. Foldable Time!!!
On the FRONT of the Lipid door, color code your elements. C=green, O=blue, H=red
On the INSIDE of the Lipid door, write TWO functions, list all elements present, write the name of the monomer
On the nutrition label to the left of the function flap, highlight the lipids yellow

20. Soup Label Debate

21. Name the biomolecule….Carb or Lipid?
